RTV2 Tin cure Liquid Silicone Mold Rubber for Gypsum,Plaster,
Concrete Mold Making
Description of Mold Making Silicone rubber
RTV2 Tin-based silicones, also called condensation cure silicone,
are two-component materials which can cure at room temperature to
flexible, high tear-strength rubbers. Tin cured silicone can be
poured onto models or they can be made brushed by adding a
thixotropic additive. They are ideal for molds where easy release
or high temperature resistance (Max 200 C) is required.
Characteristics of Mold Making Silicone rubber
Tin cure silicone rubber for molding is white or translucent
flowing liquid with general hardness of 15-60shore A after curing.
Molding silicone rubber is a kind elastic silicone rubber mold
which features with resistance to deformation, high-temperature,
acid-alkali and expansion as well as high reproduction times, good
tensile strength, tear strength and elongation, Stripping the
gender is good, Linear shrinkage rate low, Size stability is good.
Applications of Mold Making Silicone rubber
Tin cured silicone can be used for casting polyurethane, epoxy,
polyester resin, PU resin, cement, plaster, gypsum, candle, soap,
waxes, toys crafts, poly resin crafts, Lighting, plastic toys,
stationery gifts, statue, relieve furniture, furniture decorative
materials, artificial stone, building decoration material,
sculpture, sandstone, low melt alloys/metals, urethane and so on.
Instructions for Mold Making Silicone rubber
1. Make sure the surface of the original is clean and free of loose
material.
2. Weight 100 Part A base and 2 parts of CA30 Curing Agent in a
clean container.
3. Stir Part A base silicone before use thoroughly, as filler
separation may occur upon prolonged storage.
4. Mix Part A and Part B evenly until the CA30 completely dispersed
in the base.
5. Pour the mixed Part A base silicone and CA-30 curing agent as
soon as possible onto the original
6. De-mold after 24 hours, it will improve the replicate times of
silicone mold.
Note: It is strongly recommended that entrapped air be removed in a
vacuum chamber, allowing the mix to completely expand and then
collapse. After a further 1-2 minutes under vacuum, the mix should
be inspected and can be used if free of air bubbles. A volume
increase of 3-5 times will occur on vacuum de-airing the mixture.
So a suitably large container should be chosen.
